In a method for processing a signal received by a receiver, at a first wireless receiver (20, 62) a first signal (x(t), x1(t)) comprising first and second signal components is received. The first signal component is intended for the first wireless receiver (20, 62) and the second signal component is related to at least one of a sending signal (s(t)) generated by a transmitter (29, 69) or to a second signal (x2(t)) intended for a second wireless receiver (61). To the first wireless receiver (20, 62) a reference signal (r(t), r1(t), r2(t)) which is proportional to the sending signal (s(t)) or to the second signal (x2(t)). At the first wireless receiver (20, 62) and from the reference signal (r(t), r1(t), r2(t)) an estimation signal which estimates the second signal component is generated. A filtered signal (y(t), y1(t)) is generated by subtracting the estimation signal from the first signal (x(t), x1(t)).
